California mediation is a confidential settlement process in which a neutral third party helps disputing sides reach their own agreement, used across family, civil, and employment cases and protected by some of the strongest confidentiality rules in the country under Evidence Code Sections 1115 through 1128. The mediator does not decide anything. You do. And whether the deal you reach actually holds up in court depends on specific language the written agreement has to contain.
When You’ll Encounter Mediation in California
If you have a contested custody or visitation issue, mediation is not a choice. Family Code Section 3170 requires the court to send those disputes to mediation before a judge will hear them.1Justia Law. California Family Code 3170-3173 The idea is to get parents building a parenting plan together rather than leaving it to a stranger in a robe.
In general civil cases, courts have been pushing parties toward mediation since the Civil Action Mediation Act (Code of Civil Procedure Section 1775 and following), which authorizes referral to mediation particularly where the amount in dispute does not exceed $50,000.2California Legislative Information. California Code of Civil Procedure 1775 Even outside that program, judges routinely encourage mediation in contract, personal injury, real estate, and employment disputes. Employment matters tend to benefit especially, because a private resolution avoids public exposure and can include terms like agreed job references or structured payments that no court would ever order.
Federal courts sitting in California use mediation too. Under Federal Rule of Civil Procedure 16, a judge can order parties to appear for pretrial settlement conferences and require that someone with authority be available to discuss resolution.3Legal Information Institute (Cornell Law School). Rule 16 Pretrial Conferences, Scheduling, Management Most federal districts in the state run their own ADR programs that steer cases to mediation early.
How The Process Actually Works
Preparation starts before you walk in. Each side (usually through counsel) submits a confidential mediation brief laying out the facts, the legal issues, and a settlement position. The mediator reads these in advance to find where common ground might exist.
The session itself typically opens with everyone in one room. The mediator sets ground rules, stresses confidentiality, and lets each side speak without interruption. Those opening statements matter more than people expect. Hearing the other side describe the dispute in their own words, rather than through pleadings or lawyer letters, often shifts how the room feels.
After that, the mediator usually splits the group into private caucuses and shuttles between them. This is where most of the real work happens. The mediator can be candid about weak spots in your case, probe what you actually need as opposed to what you’ve been demanding, and test movement without the other side watching. Offers and counteroffers travel back and forth until the gap closes or the mediator calls an impasse. Some disputes resolve in a few hours. Complex commercial matters can stretch across multiple sessions over weeks.
What It Costs
Private mediator rates in California generally run from about $200 to $1,000 per hour, depending on experience, complexity, and location. San Francisco and Los Angeles tend to run higher than smaller markets. For a straightforward half-day, each side might pay $1,000 to $2,500 for the mediator alone, with attorney time on top. Complex multi-party commercial mediations can run considerably higher.
Court-connected programs are cheaper. Some offer reduced-rate or volunteer mediators, particularly for cases referred under the Civil Action Mediation Act. Even at private rates, mediation almost always costs less than running a case through discovery and trial, which is a large part of why judges push it so hard.
Picking a Mediator
Parties pick a mediator either by agreement or through a court-connected panel. California has no statewide licensing requirement, though the Dispute Resolution Programs Act has long required at least 40 hours of basic mediation training for mediators in court-connected programs.4UC Davis Continuing and Professional Education. 40-Hour Mediation
SB 940, effective January 1, 2025, created a voluntary statewide certification program for mediators and other ADR professionals. Certified mediators need at least 40 hours of qualifying training (with at least 25 hours from a single comprehensive course), eight hours of continuing education every two years, and a minimum number of recent mediations to show active practice.5American Arbitration Association. Mediation Aspects of SB940 in California Because the program is voluntary, uncertified mediators can still practice, but certification gives you a way to verify credentials. Many court panels add their own requirements, sometimes including minimum years of legal or professional experience.
Whatever credentials your mediator holds, the role is strictly neutral. The Evidence Code defines a mediator as a neutral person who conducts the mediation, including anyone designated to help with preparation.6California Legislative Information. California Evidence Code 1115 – Mediation Definitions A mediator cannot rule, decide who is right, impose an outcome, or give legal advice. What they can do is help each side see their own strengths and weaknesses, surface creative options, and keep conversations productive when tempers rise. That’s the line between mediation and arbitration: in arbitration, someone else decides for you; in mediation, you decide for yourself.
What Stays Confidential (And What Doesn’t)
The core protection sits in Evidence Code Section 1119. Nothing said or admitted during mediation is admissible or discoverable in a later noncriminal proceeding. No document prepared for or during mediation is admissible or discoverable. All communications and settlement discussions between participants stay confidential.7California Legislative Information. California Evidence Code 1119 – Mediation Confidentiality In practice, you can float an offer, acknowledge a weakness, or test a creative proposal without worrying it will resurface in court if the mediation falls apart.
Watch that “noncriminal” qualifier. Statements made in mediation could potentially be used in a criminal proceeding. It’s a narrow but real limitation.
Under Section 1121, the mediator cannot submit any report, evaluation, or recommendation to the court about what happened in the session. If a court rule requires it, the mediator can only report whether the parties reached an agreement.8California Legislative Information. California Evidence Code 1121 – Mediator Reports The judge will not hear from the mediator which side was unreasonable.
The protections are broad but not absolute. Section 1120 preserves the most important carve-out: evidence that was already admissible before the mediation does not become shielded just because someone brought it up during the session.9California Legislative Information. California Evidence Code 1120 – Evidence Not Excluded A contract, a photograph, or a financial record that would be admissible on its own stays admissible. The statute also does not prevent disclosure of the simple fact that a mediator was retained, and financial disclosures required under Family Code Sections 2104 and 2105 remain admissible even if prepared during mediation.
Under Section 1122, mediation communications can be disclosed if all participants expressly agree in writing or on the record before the mediator.10California Legislative Information. California Evidence Code 1122 – Disclosure Conditions A narrow exception also allows limited use in attorney disciplinary proceedings tied to the Section 1129 disclosure obligations, as long as what was actually said in mediation stays out.
Making Your Settlement Agreement Stick
Here’s the part that trips people up. Reaching a handshake deal at the table doesn’t give you a deal a court will enforce. Confidentiality can swallow your own agreement if you don’t draft it correctly.
Under Evidence Code Section 1123, a written settlement agreement prepared during mediation becomes enforceable only if it is signed by the settling parties and meets one of these conditions:11California Legislative Information. California Evidence Code 1123 – Written Settlement Agreement Admissibility
- The agreement states that it is enforceable, binding, or words to that effect.
- The agreement states that it is admissible or subject to disclosure.
- All parties expressly agree in writing or orally on the record to its disclosure.
- The agreement is used to show fraud, duress, or illegality relevant to a disputed issue.
If the writing doesn’t include language saying it is enforceable or admissible, it stays protected by confidentiality, which means you cannot bring it to court to enforce. The practical rule: get a signed writing before anyone leaves the room, and make sure it says in plain terms that it is binding, enforceable, and admissible.
Oral agreements are treated separately under Section 1124. An oral deal made during mediation can be admissible, but only if it was recorded and meets the procedural requirements of Section 1118, generally meaning it was made before the mediator and on the record.12California Legislative Information. California Evidence Code 1124 – Oral Agreement Admissibility Relying on an oral agreement is risky. Reduce the deal to a signed writing before the session ends, even if it is just a short-form memorandum with a longer document to follow.
Taxes On The Settlement Money
If your mediation produces a payment, the tax treatment depends on what the payment is for, and the time to settle that question is at the table, not after checks have been cut. Under 26 U.S.C. § 104, damages received on account of personal physical injuries or physical sickness are excluded from gross income.13Office of the Law Revision Counsel. 26 USC 104 – Compensation for Injuries or Sickness Emotional distress alone doesn’t qualify as a physical injury under that exclusion, though medical expenses attributable to emotional distress can be excluded up to the amount actually paid for the care.
Settlements for non-physical claims, such as employment discrimination, breach of contract, or defamation, are generally taxable as ordinary income. How the agreement allocates the money matters. The IRS will typically respect the allocation if it is consistent with the nature of the underlying claims.14Internal Revenue Service. Settlements – Taxability (Publication 4345) In cases blending physical and non-physical claims, a thoughtful allocation between taxable and non-taxable components can save thousands.
If Mediation Doesn’t Settle The Case
Not every mediation produces a deal, and that isn’t a disaster. When the mediator calls an impasse, the case returns to whatever track it was on. In family matters, the court moves ahead to hear the contested custody or visitation issues, and the judge decides what the parents couldn’t. In civil cases, the parties go back to discovery, motions, and eventually trial or renewed settlement talks.
You can return to mediation voluntarily at any time before final judgment. A case that felt unresolvable early on often becomes settleable after discovery changes the picture or trial costs become concrete. And the confidentiality rule in Section 1119 means that nothing from the failed mediation follows the case into the courtroom. Neither side can tell the judge what the other offered or admitted.7California Legislative Information. California Evidence Code 1119 – Mediation Confidentiality
